Description

Door lock with adjustable handle angle

The invention relates to a door lock, in particular to a door lock with adjustable handle angle.

As shown in FIGS. 1 and 2, a conventional channel lock includes a lock case 1, a lock tongue 2 movably disposed on the lock case 1, and a left and right movably disposed on the lock case 1. A linking member 3 connected to the lock tongue 2 and a second tensile spring 4 connected between the linking member 3 and the lock housing 1 are rotatably disposed in the lock housing 1 and have a mounting hole 501 A handle knob 5, a second tension spring 6 connected between the handle knob 5 and the lock case 1, and a handle 7 installed in the mounting hole 501. Thereby, the first tensile springs 4 can drive the linking member 3 to drive the lock tongue 2 to the left relative to the lock housing 1 to extend beyond the lock housing 1 so that the door can be closed and used as When a person holds the handle 7 and rotates the handle knob 5 in a clockwise direction, the handle knob 5 can drive the lock tongue 2 to retract to the right through the link 3 to open the door.

However, such a channel lock cannot adjust the horizontal state of the handle 7 when the handle 7 is installed. Therefore, the handle 7 will often sag slightly after assembly is completed due to problems in production tolerances or assembly tolerances of the parts. In the upturned state, for example, if the portion of the lock housing 1 that is in contact with the top surface of the handle knob 5 is too large in the upper and lower directions, it may cause the handle knob 5 to turn more clockwise. Angle, so that the handle 7 appears to be slightly drooped, or the second tension spring 6 pulls the handle knob 5 to rotate a few angles counterclockwise, so that the handle 7 appears slightly upturned, where All of these will affect the appearance of the quality of this channel lock.

It is therefore an object of the present invention to provide a door lock with an adjustable handle angle that overcomes at least one of the disadvantages of the prior art.

An inserting groove 713, an outer hole 714 communicating with the nut inserting groove 713, and an inner hole 715 communicating with the nut inserting groove 713 and opposite to the outer hole 714. In the first embodiment, the adjustment slider 71 is interposed between the pushed surface 521 of the handle knob 50 and the guide block portion 114, and is in sliding contact with the guide block portion 114.

The adjusting nut 72 is inserted into the nut insertion groove 713 and has a locking hole 721.

The adjusting bolt 80 is rotatably but immovably disposed on the main housing 11 of the lock housing unit 10. The adjusting bolt 80 has a head 81 and a screw portion 82. The screw portion 82 of the adjusting bolt 80 passes through. The outer hole 714 of the adjusting slider 71 is screwed to the locking hole 721 of the adjusting nut 72. The adjusting bolt 80 is used to drive the slider module 70 to drive the handle knob 50 along the second rotation direction θ2. Turn. In the first embodiment, the head 81 of the adjustment bolt 80 is a frusto-conical section in the cross section of the bolt insertion groove 116 engaged with the mounting block 115, so that the adjustment bolt 80 can be relatively The main housing 11 rotates but cannot move relative to the main housing 11 along the first axis X.

Therefore, as shown in FIG. 9, after the door lock 100 is assembled, if the handle 200 is slightly upturned, as shown in FIG. 10, the user can use a hand tool (not shown, such as a screw) Screwdriver) into the adjustment opening 117 of the main housing 11 to rotate the adjustment bolt 80 so that the adjustment bolt 80 drives the slider module 70 to move to the left along the first axis X, the adjustment slider The pushing surface 711 of 71 pushes the pushed surface 521 of the handle knob 50, forcing the handle knob 50 with the handle 200 to rotate in the second rotation direction θ2 (clockwise), so that the handle 200 returns To the horizontal state.

Conversely, as shown in FIG. 11, after the door lock 100 is assembled, if the handle 200 is in a slightly sagging state, as shown in FIG. 12, the user can also extend the hand tool into the main housing 11. The adjustment opening 117 to rotate the adjustment bolt 80 so that the adjustment bolt 80 drives the slider module 70 to move to the right along the first axis X, and the elastic restoring force of the second elastic element 60 will be pulled The handle knob 50 forces the handle knob 50 to rotate the handle 200 along the first rotation direction θ1 (counterclockwise), thereby returning the handle 200 to a horizontal state.

Through the above description, the advantages of the present invention can be summarized as follows:

According to the present invention, the design of the second elastic element 60 in combination with the slider module 70 and the adjustment bolt 80 can be used to finely adjust the angle of the handle knob 50 and the handle 200 under normal conditions by turning the adjustment bolt 80. According to the known technology, the present invention can effectively overcome the problem of production tolerance or assembly tolerance of the parts, so that the handle 200 can be adjusted to a horizontal state after the door lock 100 is assembled, effectively improving the overall appearance quality of the door lock 100 Look and feel.

Referring to FIGS. 13 and 14, a second embodiment of the present invention is similar to the first embodiment. The difference between the second embodiment and the first embodiment lies in:

As shown in FIGS. 15, 16 and 17, the second embodiment is a channel lock and includes two first elastic elements 40 spaced apart from each other. The linkage mechanism 30 is a one-piece structure. The component 40 is connected between the linkage mechanism 30 and the main casing 11 of the lock housing unit 10.

The handle knob 50 further includes a connecting end portion 54 extending from the central portion 51. The second elastic element 60 is connected between the connecting end portion 54 and the main casing 11 of the lock housing unit 10.

The slider module 70 is movably disposed on the lock housing unit 10 along a second axis Y that intersects the first axis X. The adjustment slider 71 is interposed between the first axis X and the first axis X. The pushed surface 521 of the handle knob 50 is in sliding contact with the guide block portion 114.

Therefore, after the door lock 100 is assembled, if the handle 200 is slightly upturned, the user can also insert the hand tool into the adjustment opening 117 of the main casing 11 to rotate the adjustment bolt. 80, the adjustment bolt 80 drives the slider module 70 to move downward along the second axis Y, and then the pushing surface 711 of the adjusting slider 71 also pushes the pushed surface 521 of the handle knob 50, forcing The handle knob 50 carries the handle 200 in the second rotation direction θ2 (clockwise), so that the handle 200 returns to a horizontal state.

Conversely, after the door lock 100 is assembled, if the handle 200 is in a slightly sagging state, the user can also insert the hand tool into the adjustment opening 117 of the main housing 11 to rotate the adjustment bolt 80 If the adjustment bolt 80 drives the slider module 70 to move upward along the second axis Y, the elastic restoring force of the second elastic element 60 will pull the knob 50 and force the knob 50 With the handle 200 turned in the first rotation direction θ1 (counterclockwise), the handle 200 is returned to a horizontal state.

In this way, the second embodiment can also achieve the same purpose and effect as the first embodiment described above.

To sum up, the door lock with adjustable handle angle of the present invention can not only overcome the problem of production tolerance or assembly tolerance of parts, but also allow the handle to be adjusted to a horizontal state after the door lock is assembled, so it can be achieved. Object of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
